Chinese Abstract

應用古地磁學原理,分析了中國北方第四紀黃土、泥河灣盆地、黃海陸架磁性地層記錄的古地磁極倒轉與氣候變化之間的關係。研究表明第四紀古地磁極倒轉與氣候變化有一定的耦合關係:Matuyama/Gauss極性界限、Brunhes/Matuyama極性界限與第四紀氣候變冷期相對應,Matuyama負極性時中的正極性亞時及Brunhes正極性時中的負極性亞時與氣候變暖期相一致。因而,第四紀古地磁極倒轉可能是第四紀氣候冷暖波動變化的主要驅動因素之一。

English Abstract

This paper analyzed the relationship between paleomagnetic polarity reverse and climatic change recoded by magnetostratigraphy of loess, Nihewan Basin and Yellow Sea shelf in Northern China during Quaternary by paleomagnetism. The sdudy indicate that the coupling exists in between paleomagnetic polarity reverse and climatic change during Quaternary: Matuyama/Gauss polarity transition and Brunhes/Matuyama polarity transition correspond with climatic chill period during Quaternary. Normal polarity subchron of Matuyama reverse polarity chron and reverse polarity subchron of Brunhes normal polarity chron correspond with climatic warm period. Therefore, paleomagnetic polarity reverse of Quaternary may be one of the main driving factors.
